Second-hand intermediary is more suitable for places with large liquidity and relatively developed economy. These two factors are important sources of selling used cars.

If the place is small, you can't make much money anyway.

Since you are an intermediary, buy a used car at a low price and sell it at a high price to earn the difference, but if you don't know much about cars, it is more risky.

The most common way is to collect management fees from sellers to get information about used cars and then promote them. In addition, if you buy a car from you, you can also charge an appropriate amount of information fees.
